To all whom it may concern.-

Be it known that we, WILLIAM J. LLOYD and JOHN R. ANDERSON, citizens of the United States, residing, respectively, at Rugby, England, and at Pittsfield,

county of Berkshire, State of Massachusetts, have invented certain new and useful Improvements in Machines for Preparing Paper for Curve-Drawing Instruments, of which the following is a specification.

This invention relates to mechanism for preparing paper for use in recording instruments and has for its object the provision of a machine of this character which will automatically perform the desired operations upona web of paper as it is passed through the machine in an accurate and rapid manner, and which at the same time is simple of construction and operation and can be built at a low cost.

More specifically our invention relates to the preparation of paper for curve drawing instruments. In instruments of this character a narrow web of paper is gradually fed through the machine which traces thereon a curve or curves showing conditions which it is desired to record. Longitudinal and cross-lines are provided to represent the abscissa: and ordinates of the curve, the cross-lines usually indicating time, and the hour being printed adjacent thereto at intervals. In order that the sheet shall travel through the curve drawing instrument in an absolutely accurate manner without slip, it is perforated preferably along the margin so as to engage a toothed driving wheel in the curve drawing instrument.

Our invention consists in the features of construction and in the arrangement and combination of elements hereinafter set forth and particularly pointed out in the claims annexed to and forming a part of this application.

In the drawings, Figure 1 is a side elevation of a machine embodying our invention, certain parts being broken away for purposes of clearness; Fig. 2 is an end elevation of the same; Fig. 3 is a sectional view taken approximately on the line 33 of Fig. 1; Fig. 4 is a detail of the printing mechanism; Fig. 5 is a detail of the cross-lining mechanism and the inking pad therefor; Fig. 6 is a detail of the mechanism for operating the feed roll; Fig. 7 is anotl1er view of the same; Fig. 8 is a detail of the bearing for the paper roll; and Fig. 9 shows a fragment of the finished paper. 7

Briefly stated, our device comprises four correlated mechanisms for simultaneously performing certain op erations upon a strip of paper. As the paper is fed through the machine, it travels under a set of ruling pens through which ink is continuously flowing and which trace thereon parallel lines. The paper then travels under a reciprocating head provided with a punch which perforates the margin of the paper and presses a cross-line upon the paper opposite to the perforations. Simultaneously with these operations, as the head travels downward, it strikes a lino-type-carrier and prints the time on the margin of the paper opposite the perforations and adjacent to the cross-lines. The paper is then wound on a roll at the opposite end of the machine.

Referring to the drawings, 1 is the pedestal of the machine surmounted by a casting 2 bolted thereto and forming the main frame of the machine. This casting has a fiat table portion 3 and has bolted thereto extension brackets 4 and 5 having their upper surface flush with the top 3 so as to make a long level table over which the paper travels. The back of the casting rises considerably above the table portion and is G-shaped, as shown. On top of this C-shaped frame is mounted a horizontal shaft 6 having bearings 7 and 8 and provided with an eccentric 9 and a driving pulley 10, the axis of the shaft being at right angles to the length of the paper table. A type-carrying wheel 11 is loosely mounted upon this shaft and is of such a diameter that its periphery extends almost to the paper table. A sliding head 12 is mounted in guides 13 in the main frame and is reciprocated by the eccentric 9 through the connectingrod 14, pivoted at 15. The head 12 carries a punch 16 at its lower end for perforating the paper on the table. A pair of feeding rolls 17 and 18 are mounted in the main frame and geared together by gears 19 and 20. The shaft of the roll 17 is extended beyond the gear and is provided with a driving ratchet 2].. Pivoted to the bracket 5 at 22 is a lever 23 having one end connected to the reciprocating head at 24 by a link 25 and having its opposite end provided with a spring-pressed pawl 26. As the head travels downward the pawl slips over the ratchet and the rolls remain stationary, but when the head moves upward the pawl engagesthe ratchet and rotates the same stepping the paper through the machine, the length of the step depending upon the arrangement of the pivotal point of the lever. A toothed wheel 27 is likewise mounted upon the shaft of the roll 18, the teeth of which travel in the groove of the Wheel 28 on the shaft of roll 17. This toothed wheel has the same dimensions as the drive wheel of the instrument in which the paper is to be used, and as the paper passes between the wheels 27 and 28, the teeth check up the perforations and prevent the slipping of the paper. A wiper 29 is also provided adjacent to the roll 18 and makes contact therewith so as to clean the roll of ink after the paper has passed over it.

The mechanism whereby the cross-lines are pressed upon the sheet of paper is as follows: a crank 30 is pivoted to the sliding head at 31, and has its free end connected to a connecting-rod consisting of the telescoping parts:32 and 32, held together by the tension of the spring 33. The free end of this connecting-rod is pivoted to the frame of the machine at 34. The crank 30 is secured to a rock-arm having a bearing in the sliding head and extending forward over the paper table. A line stamp 35 is resiliently mounted in this arm by means of the pins 36 and 37 and the springs 38 and 39.

These springs are for the purpose of cushioning the stamp so as to make a good printing contact with the paper. It will be seen that as the sliding head moves downward, the stamp will be drawn around to a vertical position, and as the motion continues alittle farther, the telescoping connecting-rod lengthens out slightly and the stamp prints a cross-line upon the paper. On the upward stroke. the two sections of the connecting-rod contract and the stamp is again drawn into a horizontal position. The stamp is brought around to this position for the purpose of inking ii and this is accomplished by means of a lever 40 pivoted at 41 to the frame of the machine and carrying at its lower end an inking pad 42. The upper end of the lever is provided with a roller 43 adapted to be engaged by a cam 44 keyed to the shaft 6. This cam is so arranged on the shaft that at the moment the sliding head is up and the stamp is in a horizontal position, it will force the pad into contact with the stamp, as shown in Fig. 5.

In order to print the hours of the day at intervals along the margin of the sheet, we provide the following mechanism: the wheel 11 is provided on its periphcry with preferably twenty-four type-holders 45, one for each hour of the day. These type-holders are spring-pressed upward by means of the springs 46, but are adapted to be pushed downward a short distance when struck on the inner end. These type-holders carry logotypes to indicate the hour of the day, the numbers being arranged to successively increase around the circumference. The sliding head is provided with a lug 47 extending forward and terminating just over the one of the type-holders which occupies the lowest position. This lug is. provided with an adjustable pin 48 adapted to successively impinge the reduced end of each type carrier as the lug is carried downward by the sliding head so as to cause the type to successively print upon the sheet. An inking roll 48 is pivoted to arm 49 secured to the frame so that the type as they pass this roller will be successively inked once in each revolution.

Rigidly secured to the inside of the wheel 11 and concentric therewith is a ratchet toothed wheel 49. The teeth of this ratchet are engaged by a spring-pressed pawl 50 pivoted at 51 to the lever 52 which is pivoted at 53 to the frame of the machine. The free end of this lever is connected to the sliding head at 54 by means of the link 55. As the sliding head moves up the pawl engages the teeth, carrying the type-holding wheel an amount equal to the distance between type-holders, and upon its descent the pawl slips past the teeth.

A roll for blank paper 56 is journaled at 57 in downwardly projecting lugs on bracket 4. In order to quickly change the rolls, we provide the means shown in Fig. 8. This consists of a bolt 58 slidably mounted in the frame and having its inner end supporting the mandrel upon which the paper is wound. The bolt 58 is grooved at 59 to admit a sliding pin 60 which is spring-pressed toward the bolt by means of the spring 61. This pin slides through the screw 61 and terminates in the knurled head 62 by means of which it is moved outward against the tension of spring 61 torelease bolt 58.

As the paper leaves the roll 56 it passes under a tightener 68 over the roller 64 and under the lining pens 65. This ruling device forms no part of our invention and may be of any desired type, the only requisite being that they operate continuously to trace parallel lines at predetermined distances apart.

Under the inking pens we provide heating coils 65 so as to dry the ink before it passes on through the machine. After the paper passes under the sliding head and the operations above described have been performed upon it, it passes onto a roll 66 which is rotated by means of a sheave 67 and a belt 68 driven by a sheave 69 on the shaft 6.

The operation of our device will be clearly understood from the above description. The shaft 6 is continuously rotated by means of the pulley 10, giving the sliding head a reciprocating motion toward and from the paper. As the head descends, it punches or cuts the holes 70 along the margin of the paper and at the same time the lining stamp impresses a crossline 71 opposite the perforation. Simultaneously with these operations, the extension on the sliding head strikes the type-holder and prints the hour on the opposite side of the cross-line from the perforations.

In Fig. 9 we have shown the cross-lines printed six to the hour, or ten minutes apart, but this of course may be varied to suit the special requirements of the machine in which it is to be used. In the arrangement shown, upon every sixth revolution of the pulley, a type-holder comes into position over the paper and is struck by the projecting lug on the sliding head. The paper then passes through the feed rolls over the toothed wheel 27 and onto the roll 66, from which it may be removed for use in the curve drawing instrument.
